SIMPLE CONFIGURATION: MEDIA GATEWAY TO ACCESS PSTN NETWORKS GXW-410xv can be configured to work with any leading SIP server, for a pure media gateway to access PSTN networks. In such applications, the user only needs to configure GXW-410xvgateway Stage Dialing field and Sip Server field. For a simple set-up, users only need to configure a SIP server field for default SIP Profile 1. This field should be configured to point to the SIP server to be used with the GXW-410xv. For advanced applications, the user is required to choose at least one SIP server field from the SIP profiles and one stage dialing under system Channel configuration table. On SIP server sides, the SIP server must be configured to forward user PSTN calls to the GXW-410xv. Please be aware that by default, the system uses North American PSTN settings and TWO STAGE dialing to access PSTN networks for VOIP to PSTN calls and PSTN to VOIP calls. Two stage dialing means the end-user will hear dial-tone twice. First dial-tone is used to let users to input destination number in the same network of the calling networks. Second dial-tone is used to let users to input final destination number.


The GXW-410xv also supports ONE STAGE dialing, which means users only need to input one final

CONFIGURATION GUIDE CONFIGURATION WITH WEB BROWSER The GXW-410xv has an embedded Web server that will respond to HTTP GET/POST requests. It also has embedded HTML pages that allow a user to configure the IP phone through any common web browser. Examples of GUI interfaces can be downloaded @ http://www.grandstream.com/GUI/GUI_GXW-410xv. ACCESSING THE WEB CONFIGURATION MENU

1. Connect the Power to the GXW-410xv unit. 2. Connect an Ethernet cable between the LAN port on GXW-410xv to your PC. 3. You will have to assign a dummy IP with the same subnet as the GXW IP Address, which is

192.168.0.160 by default. So, set an IP address like 192.168.0.x for your PC. 4. Launch web browser and type http://192.168.0.160 at address of web browser. This connects you

to the GXW-410xv web server. You may choose to use DHCP or PPPoE connection or another static IP address according to your local network environment. The Gateway Web Configuration Menu can be then accessed by the following URI: http://Gateway-IP-Address where the Gateway-IP-Address is the IP address of the Gateway. NOTE: To access the configuration page, type the GXW IP address into the browser, stripping out the leading “0” because the browser will parse in octet. e.g. if the IP address is: 192.168.001.014, please type in: 192.168.1.14.

Layer 2 QoS This contains the value used for layer 2 VLAN tag. Default setting is blank.

Inter Digit Timeout

Default is 4 seconds.

Local RTP port This parameter defines the local RTP-RTCP port pair the GXW-410xv will listen and transmit. It is the base RTP port for channel 0. When configured, channel 0 will use this port _value for RTP and the port_value+1 for its RTCP; channel 1 will use port_value+2 for RTP and port_value+3 for its RTCP. The default value is 5004.

Use Random Port

This parameter, when set to Yes, will force random generation of both the local SIP and RTP ports. This is usually necessary when multiple GXW-410xvs are behind the same NAT.

Keep-alive interval

This parameter specifies how often the GXW-410xv sends a blank UDP packet to the SIP server in order to keep the “hole” on the NAT open. Default is 20 seconds.

Firmware Upgrade & Provisioning

This radio button will enable GXW-410xv to download firmware or configuration file through either TFTP or HTTP.

Via TFTP Server

This is the IP address of the configured TFTP server. If selected and it is non-zero or not blank, the GXW410x will attempt to retrieve new configuration file or new code image from the specified TFTP server at boot time. It will make up to 5 attempts before timeout and then it will start the boot process using the existing code image in the Flash memory. If a TFTP server is configured and a new code image is retrieved, the new downloaded image will be verified and then saved into the Flash memory. Note: Please do NOT interrupt the TFTP upgrade process (especially the power supply) as this will damage the device. Depending on the network environment this process can take up to 15 or 20 minutes.

Via HTTP Server

The URL for the HTTP server used for firmware upgrade and configuration via HTTP. For example, ttp://provisioning.mycompany.com:6688/Grandstream/1.0.0.36 Here “:6688” is the specific TCP port that the HTTP server is listening at, it can be omitted if using default port 80. Note: If Auto Upgrade is set to No, GXW-410xv will only do HTTP download once at boot up.


Automatic Upgrade

Choose Yes to enable automatic upgrade and provisioning. In “Check for new firmware every” field, enter the number of days to enable GXW-410xv to check the server for firmware upgrade or configuration in the defined period of days. When set to No, GXW-410xv will only do upgrade once at boot up. “Always check for New Firmware.” Check New Firmware only when F/W pre/suffix changes”

Syslog Server The IP address or URL of System log server. This feature is especially useful for ITSP (Internet Telephone Service Provider)

Syslog Level Select the ATA to report the log level. Default is NONE. The level is one of DEBUG, INFO, WARNING or ERROR. Syslog messages are sent based on the following events:

1. product model/version on boot up (INFO level) 2. NAT related info (INFO level) 3. sent or received SIP message (DEBUG level) 4.

If the GXW-410xv has an assigned PSTN telephone number, this field should be set to “Yes”. Otherwise, set it to “No”. If “Yes” is set, a “user=phone” parameter will be attached to the “From” header in SIP request.

SIP Registration This parameter controls whether the GXW-410xv needs to send REGISTER messages to the proxy server. The default setting is “Yes”.

Unregister on Reboot

Default is No. If set to yes, the SIP user’s registration information will be cleared on reboot.

Register Expiration

This parameter allows the user to specify the time frequency (in minutes) for the GXW-410xv to refresh its registration with the specified registrar. The default interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days).

Local SIP port This parameter defines the local SIP port the GXW-410xv will listen and transmit. The default value for Account 1 is 5060. It is 5062, 5064, 5066 for Account 2, Account 3 and Account 4 respectively.

NAT Traversal This parameter defines whether the GXW-410xv NAT traversal mechanism will be activated or not. If activated (by choosing “Yes”) and a STUN server is also specified, then the GXW-410xv will behave according to the STUN client specification. Under this mode, the embedded STUN client inside the GXW-410xv will attempt to detect if and what type of firewall/NAT it is sitting behind through communication with the specified STUN server. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the GXW-410xv will attempt to use its mapped public IP address and port in all of its SIP and SDP messages. If the NAT Traversal field is set to “Yes” with no specified STUN server, the GXW-410xv will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.

Proxy-Require SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

Early Dial Default is No. Use only if proxy supports 484 response.

Session Expiration

Grandstream implemented SIP Session Timer. The session timer extension enables SIP sessions to be periodically “refreshed” via a SIP request (UPDATE, or re-INVITE. Once the session interval expires, if there is no refresh via a UPDATE or re-INVITE message, the session will be terminated. Session Expiration is the time (in seconds) at which the session is considered timed out, if no successful session refresh transaction occurs beforehand. The default value is 180 seconds.


Min-SE The minimum session expiration (in seconds). The default value is 90 seconds.

Caller Request Timer

If selecting “Yes” the phone will use session timer when it makes outbound calls if remote party supports session timer.

Callee Request Timer

If selecting “Yes” the phone will use session timer when it receives inbound calls with session timer request.

Force Timer If selecting “Yes” the phone will use session timer even if the remote party does not support this feature. Selecting “No” will allow the phone to enable session timer only when the remote party support this feature. To turn off Session Timer, select “No” for Caller Request Timer, Callee Request Timer, and Force Timer.

UAC Specify Refresher

As a Caller, select UAC to use the phone as the refresher, or UAS to use the Callee or proxy server as the refresher.

UAS Specify Refresher

As a Callee, select UAC to use caller or proxy server as the refresher, or UAS to use the phone as the refresher.

Force INVITE Session Timer can be refreshed using INVITE method or UPDATE method. Select “Yes” to use INVITE method to refresh the session timer.

Enable 100rel The use of the PRACK (Provisional Acknowledgment) method enables reliability to be offered to SIP provisional responses (1xx series). This is very important if PSTN inter-networking is to be supported. A user’s request to use reliable provisional responses is invoked by the 100rel tag which is appended to the value of the required header of initial signalling messages.

Send Anonymous

If this parameter is set to “Yes”, the “From” header in outgoing INVITE message will be set to anonymous, essentially blocking the Caller ID from displaying.

Preferred Vocoder

The GXW-410xv supports up to 5 different Vocoder types including G.711 A-/U-law, GSM, G.723.1, G.729A/B. The user can configure Vocoders in a preference list that will be included with the same preference order in SDP message. The first Vocoder in this list can be entered by choosing the appropriate option in “Choice 1”. Similarly, the last Vocoder in this list can be entered by choosing the appropriate option in “Choice 8”.

Special Feature Default is Standard. Choose the selection to meet some special requirements from Soft Switch vendors like Nortel, Broadsoft, etc.

NO to YES, reboot the device.

2. Connect an analog based surveillance camera to the VIDEOIN connection at the back panel

of the unit.

PC side (Monitor Device):

1. Download VLC from http://www.videolan.org/vlc/. This is the only player so far that works and support RFC 3984.

2. Launch VLC. 3. Go to Preferences->Input/Codecs->Demuxers->H264, check “Advanced options” in the

bottom. The option “Frames per Second” will show. Change that value to 5 and then save. 4. Go to Preferences->Input/Codecs->Access modules->Real RTSP, check “Advanced options”

in the bottom. The option “Caching value (ms) will show. Change that value to 1000 and then save. You may change it to a smaller value to reduce the delay.

5. If the viewer is under NAT, go to Preferences->Demuxers->Access modules->RTP/RTSP, check “Advanced options” in the bottom. The option “Use RTP over RTSP (TCP)” will show. Check that option box. (Grandstream does NOT recommend this network environment)

6. Close the Preferences window and go to File->Open Network Stream: a) Select RTSP as the protocol b) Enter the URL in the format of rtsp://admin:

ADMIN_PASSWORD@DEVICE_IP_ADDRESS:DEVICE_RTSP_PORT. Change the blue text according to your configuration:

• ADMIN_PASSWORD is the device’s web configuration password for admin. • DEVICE_IP_ADDRESS is the device IP. • DEVICE_RTSP_PORT is the RTSP port setting of the device.

FIRMWARE UPGRADE Our latest official release can be downloaded from: http://www.grandstream.com/y-firmware.htm. Firmware (or software) upgrades can be done either via TFTP or HTTP. The corresponding configuration settings are on the configuration page. End users should NOT touch the configuration settings that are useful for ITSPs. To upgrade your unit firmware, follow these steps:

1. Under Advanced Settings webpage, enter your TFTP or HTTP Server IP address (or FQDN) next to the “Firmware Upgrade: Upgrade Server” field.

2. Select via TFTP or HTTP accordingly.

3. If you plan to use Automatic Upgrade, set it to “Yes”, otherwise No (this will make it check for upgrade every time you reboot).

UPGRADE THROUGH HTTP To upgrade firmware via HTTP, the field “Firmware Upgrade and Provisioning: Upgrade Via” needs to be set to HTTP. The “Firmware Server Path” should be set to where the firmware files are located. For example, the user can use the following URL in the Firmware Server Path: firmware.mycompany.com: 6688/Grandstream/1.0.0.29 where firmware.mycompany.com is the FQDN of the HTTP server. It can also be in IP address format. “:6688” is the TCP port the HTTP server listening to, default http server listens to port 80. “/Grandstream/1.0.0.29” is the RELATIVE directory to the root dir on HTTP web server.


http://www.grandstream.com/y-firmware.htm

UPGRADE THROUGH TFTP To upgrade firmware via TFTP, set the field “Firmware Upgrade and Provisioning: Upgrade Via” to TFTP. The TFTP server can be configured in either IP address format or FQDN. To configure the TFTP server via the Web configuration interface, follow these five steps:

1. Open your browser to input the IP address of the GXW-410xv. 2. Enter the admin password to enter the configuration screen. 3. Enter the TFTP server address or URL in the “Firmware Server Path” field near the

bottom of the configuration screen. 4. Once the “Firmware Server Path” is set, update the change by clicking the “Update”

button. 5. Reboot or power cycle the unit.

If the configured updating server is found and a new code image is available, the GXW-410xv will retrieve the new image files by downloading them into the GXW-410xv’s SRAM. During this stage, the GXW-410xv’s LED will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will be saved into the Flash. If TFTP fails for any reason (e.g., TFTP server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the GXW-410xv will stop the TFTP process and simply boot using the existing code image in the flash. Firmware upgrading may take as long as 20 minutes over the Internet, or just 20+ seconds if it is performed on a LAN. Grandstream recommends conducting firmware upgrades in a controlled LAN environment if possible. NO LOCAL TFTP SERVER

For users who do not have a local TFTP server, Grandstream provides a NAT-friendly TFTP server on the public Internet for users to download the latest firmware upgrade automatically. Please check the Services section of Grandstream’s Web site to obtain this TFTP server IP address. Alternatively, user can download and install a free TFTP or HTTP server in his LAN for a firmware upgrade. A free Windows version TFTP server can be downloaded from: http://support.solarwinds.net/updates/New-customerFree.cfm.

Directions For Downloading TFTP Server:

1. Unzip the file and put all of the files under the root directory of the TFTP server. 2. Put the PC running the TFTP server and the GXW–410x in the same LAN segment. 3. Go to File -> Configure -> Security to change the TFTP server's default setting from "Receive

Only" to "Transmit Only" for the firmware upgrade. 4. Start the TFTP server, in the phone’s web configuration page. 5. Configure the Firmware Server Path with the IP address of the PC. 6. Update the change and reboot the unit.

You can also download the free HTTP server from http://httpd.apache.org/ or just use Microsoft IIS web.

RESTORE FACTORY DEFAULT SETTING WARNING! Restoring the Factory Default Setting will DELETE all configuration information of the phone. Please BACKUP or PRINT out all the settings before you approach to following steps. Grandstream will not take any responsibility if you lose all the parameters of setting and cannot connect to your VoIP service provider. FACTORY RESET The ONLY way to restore default factory settings is as follows:

1. Unplug the Ethernet cable.

2. Locate a needle sized hole on the back panel of the gateway unit next to the Power connection.

3. Enter a needle like object in this hole and keep it pressed for about 7 seconds.

4. You will see the LAN port LEDs (green and orange) go off and on simultaneously; this indicates the reset went through.

5. All settings have been erased and the gateway is back to factory settings.
